9 Vegetables That Thrive in Redwood Shade (For San Lorenzo Valley Gardeners)
If you garden in Felton, Ben Lomond, Boulder Creek, or other parts of the San Lorenzo Valley, you've probably experienced the frustration of trying to grow vegetables in redwood shade. You plant tomatoes that get leggy and produce three sad fruits. You try peppers that never mature. You start to believe the old saying: nothing grows under redwoods.
Here's the thing: that saying is only half true. Sun-loving vegetables (tomatoes, peppers, squash) genuinely struggle in shade. But plenty of vegetables don't need full sun. Some actually prefer the cooler, more consistent conditions that shade provides.
The key is matching the right crops to your light conditions. Many San Lorenzo Valley gardens have spots that get 3 to 4 hours of direct sun, plus bright indirect light for several more hours. That's enough for a surprising variety of crops.
Here are nine vegetables that can actually produce in redwood shade, based on what real San Lorenzo Valley gardeners have successfully grown.
Understanding Your Shade
Before we get to the vegetables, let's clarify what "shade" means:
Full shade (less than 2 hours of direct sun): Very limited vegetable options. Focus on the first three vegetables on this list.
Part shade (2 to 4 hours of direct sun): Many more options. Most vegetables on this list will produce.
Part sun (4 to 6 hours of direct sun): Nearly all vegetables on this list thrive. You can also try sun-lovers like tomatoes (cherry varieties) with some success.
Important: Even in shady gardens, there's usually one spot that gets more sun than others. Find it. That's where you'll plant anything borderline.
Also note: morning sun is gentler than afternoon sun. A spot with 4 hours of morning sun is cooler than one with 4 hours of afternoon sun. This matters for heat-sensitive crops.
1. Lettuce and Salad Greens
Light needed: 2 to 4 hours of sun (tolerates more shade than almost any vegetable)
Why it works in redwood shade: Lettuce actually prefers shade in our climate. Full sun causes it to bolt (go to seed) and turn bitter. The cool, consistent temperatures under redwoods are ideal.
Best types for shade:
Loose-leaf varieties (Salad Bowl, Red Sails, Oak Leaf)
Butterhead types (Buttercrunch, Tom Thumb)
Romaine (Little Gem, Winter Density)
Growing tips:
Direct sow or transplant from starts. Harvest outer leaves for continuous production. Succession plant every 2 to 3 weeks for ongoing harvests. Under redwoods, you can often grow lettuce through summer, which is impossible in sunny locations.
Local success story: A Felton gardener reports growing lettuce year-round in a bed that gets only 3 hours of morning sun. "It bolts immediately in my parents' sunny Aptos garden, but mine keeps producing all summer."
2. Spinach
Light needed: 2 to 4 hours of sun
Why it works in redwood shade: Like lettuce, spinach bolts quickly in heat and sun. Redwood shade keeps it cool and productive for months.
Best varieties:
Bloomsdale Long Standing (classic savoy type)
Tyee (bolt-resistant)
Space (smooth-leaved, good for baby spinach)
Growing tips:
Direct sow in early spring or fall. Can harvest as baby greens in 25 days or wait for full leaves. Cut-and-come-again harvesting works well. In shade, spinach often produces through early summer before bolting.
Bonus: New Zealand spinach (Tetragonia) is technically a different plant but tastes similar and tolerates even more shade. Try it for summer production.
3. Arugula
Light needed: 2 to 4 hours of sun
Why it works in redwood shade: Arugula is quick-growing and shade-tolerant. It also stays mild and tender in shade; full sun makes it sharp and peppery.
Best varieties:
Astro (fast, mild)
Standard rocket arugula
Sylvetta/wild arugula (slower but more heat-tolerant)
Growing tips:
Direct sow thickly for baby arugula (harvest at 3 weeks) or thin to 6 inches for larger plants. Succession plant for continuous harvest. Goes to flower eventually but even the flowers are edible.
4. Kale
Light needed: 3 to 5 hours of sun
Why it works in redwood shade: Kale tolerates partial shade better than most brassicas. It grows slower in shade but produces perfectly edible (often more tender) leaves.
Best varieties for shade:
Lacinato (Dinosaur/Tuscan kale) — handles shade best
Red Russian — tender and shade-tolerant
Dwarf Blue Curled — compact, good for limited space
Growing tips:
Start from transplants for faster harvest. Harvest lower leaves and let plants continue growing. Kale is perennial in Santa Cruz County; a single plant can produce for 2+ years. Remove flower stalks to extend leaf production.
Local tip: In shady San Lorenzo Valley gardens, kale often tastes sweeter than in sunny locations. Less stress means less bitterness.
5. Swiss Chard
Light needed: 3 to 5 hours of sun
Why it works in redwood shade: Chard is remarkably adaptable. It produces in full sun or partial shade, handling the range of conditions found in most San Lorenzo Valley gardens.
Best varieties:
Bright Lights (colorful stems, visual appeal)
Fordhook Giant (heavy producer, classic green)
Rainbow (mix of colors)
Growing tips:
Direct sow or transplant. Harvest outer stalks while leaving the center to continue producing. A single chard plant can produce for over a year in our mild climate. Very heat-tolerant; won't bolt like lettuce.
Bonus: Chard's colorful stems add visual interest to shady garden beds that might otherwise look dull.
6. Asian Greens (Bok Choy, Tatsoi, Mizuna)
Light needed: 3 to 5 hours of sun
Why they work in redwood shade: These fast-growing greens are perfectly suited to cooler, shadier conditions. They bolt in heat and sun, so shade actually extends the harvest season.
Best types:
Tatsoi: Rosettes of spoon-shaped leaves, very cold-hardy, excellent in shade
Mei Qing Choi (baby bok choy): Compact, fast (30 to 35 days)
Mizuna: Feathery leaves, mild flavor, extremely shade-tolerant
Komatsuna: Spinach-like, very adaptable
Growing tips:
Direct sow or transplant. For baby greens, plant thickly and harvest young. For full-size heads, thin to 6 to 8 inches. Succession plant every 3 weeks for continuous harvest.
Local timing: Best planted August through March in the San Lorenzo Valley. Some shade protection extends the spring season.
7. Green Onions (Scallions)
Light needed: 3 to 5 hours of sun
Why they work in redwood shade: Green onions are surprisingly shade-tolerant. They grow more slowly than in full sun but produce perfectly usable scallions.
Best varieties:
Evergreen Hardy White
Tokyo Long White
Red Beard
Growing tips:
Start from seed, transplants, or (fastest) regrow from grocery store roots. Plant in clusters. Harvest entire plants or just snip the green tops and let them regrow. Extremely low maintenance once established.
Pro tip: Green onions don't take up much space. Tuck them into shady corners, along path edges, or between other plants.
8. Herbs: Cilantro, Parsley, Chives, and Mint
Light needed: 3 to 5 hours of sun (mint tolerates even deeper shade)
Why they work in redwood shade: These herbs actually prefer cooler conditions. Cilantro bolts almost immediately in sun but lasts for months in shade.
Best options for shade:
Cilantro: Finally a place where it doesn't bolt in two weeks! Shade-grown cilantro is a revelation.
Parsley (Italian flat-leaf or curly): Grows beautifully in partial shade.
Chives: Nearly indestructible, produces in almost any light.
Mint: Thrives in shade and moist conditions. Contains its aggressive spreading better in shadier spots. Plant in containers to prevent takeover.
Growing tips:
Direct sow or transplant. Parsley and cilantro are biennial/annual; replant annually. Chives are perennial; divide every few years. Mint is perennial and aggressive; contain it.
9. Beets and Radishes (Root Vegetables with Caveats)
Light needed: 4 to 5 hours of sun
Why they can work: Both beets and radishes tolerate partial shade, though they grow more slowly and roots stay smaller than in full sun.
Best varieties:
Beets: Detroit Dark Red, Chioggia (candy-striped), Golden (all produce smaller but edible roots in shade)
Radishes: French Breakfast, Cherry Belle (quick even in shade; 25 to 30 days)
Growing tips:
Direct sow in loose, rock-free soil. Thin appropriately. Expect smaller roots than catalog photos show. Harvest radishes promptly; they turn woody if left too long.
Honest note: Root vegetables are borderline in heavy shade. If you have a spot with closer to 5 hours of sun, that's where to put them. With only 3 hours of sun, focus on leafy greens instead.
What NOT to Grow in Redwood Shade
These vegetables really do need full sun (6+ hours) and will struggle or fail in typical San Lorenzo Valley shade:
Tomatoes (even cherry types, though they're more tolerant than slicers)
Peppers (all types)
Eggplant
Squash (summer and winter)
Cucumbers
Melons
Corn
Beans (pole and bush)
If you have even a small sunny spot (a clearing, a driveway edge, containers in a bright location), reserve it for these sun-lovers.
Tips for Improving Shade Garden Success
Maximize available light:
Limb up trees (remove lower branches) to allow more indirect light
Use reflective mulch (white plastic or aluminum foil) to bounce light onto plants
Paint nearby fences or walls white
Remove competing vegetation at ground level
Improve your soil:
Redwood soil tends to be acidic and full of competing roots. Build raised beds at least 12 inches deep to give vegetables their own space. Add lime if soil tests very acidic (below pH 5.5).
Manage moisture:
Redwood areas often have dry soil (the trees are drinking everything) or wet spots (poor drainage in shade). Check your specific conditions. Most vegetables prefer consistent moisture.
Choose the brightest spot:
Even in shaded gardens, there's usually one area that gets more light than others. Use it for your borderline crops.
Frequently Asked Questions About Shade Gardening
Can I grow tomatoes in the shade?
Honestly, no. Even shade-tolerant cherry tomatoes need 6+ hours of sun for reasonable production. If you have a sunny spot, use it for tomatoes. If not, buy tomatoes and grow what actually thrives in your conditions.
Will vegetables produce all year in redwood shade?
Many will. The cool, consistent conditions under redwoods extend the season for heat-sensitive crops. Lettuce, spinach, and asian greens can often grow year-round with only brief summer slowdowns.
Should I add lime to my soil under redwoods?
Test first. Redwood soils are often acidic (pH 5.0 to 6.0), but vegetables tolerate pH 6.0 to 6.5 fine. If your soil is below 5.5, add lime according to soil test recommendations. Over-liming is as problematic as under-liming.
How do I deal with redwood root competition?
Raised beds (12+ inches deep) help by giving vegetables their own soil zone. Line the bottom with landscape fabric to slow (not stop) root intrusion. Alternatively, grow in large containers with fresh potting mix.
Can I improve my light by trimming redwood trees?
Limbing up lower branches is generally safe and can significantly improve ground-level light. Don't top redwoods or dramatically thin their canopies, which damages tree health and is often illegal without permits. Consult a certified arborist for major tree work.
Why do my plants look so leggy?
They're stretching for light, a sign they want more sun than they're getting. Pinch back leggy growth to encourage bushier plants. Consider moving them to a brighter spot or switching to more shade-tolerant varieties.

Embrace Your Shade
Gardening under redwoods is different, but it's not impossible. Instead of fighting your conditions, work with them. Plant what actually thrives in shade. Build your meals around salads, stir-fries full of asian greens, and herbs that finally don't bolt.
Your neighbor in sunny Watsonville might grow amazing tomatoes, but they can't grow lettuce through July without it bolting immediately. You can. That's the trade-off, and it's not a bad one.
